Uses of Bisphenol A (BPA)

Bisphenol A (BPA) is an essential raw material for the synthesis of polycarbonates, epoxy resins, and high-temperature resistant polyesters. It is also used as a PVC stabilizer, plastic antioxidant, UV absorber, fungicide, etc.
As a versatile compound, BPA is extensively employed in the production of epoxy resins, polycarbonates, polyester resins, polyphenylene ether resins, and polysulfone resins. Additionally, it serves as a stabilizer for polyvinyl chloride (PVC), an antioxidant in plastics, a UV absorber, an agricultural fungicide, and an anti-aging agent in rubber.
It is also utilized as an antioxidant and plasticizer in paints and inks. In organic synthesis, BPA acts as a key ingredient for manufacturing epoxy and polycarbonate resins, and it is widely applied as an important raw material for high-molecular synthetic compounds, as well as in anti-aging agents, plasticizers, and agricultural fungicides.

Bisphenol a bpa Acid-Catalyzed Process
In the acid-catalyzed process, the catalysts are usually sulfuric acid, hydrochloric acid, or hydrogen chloride gas.
The process using sulfuric acid as a catalyst has a simple flow, is produced in a single kettle, operates intermittently, does not require phenol recovery, and has low investment. However, it has many by-products, poor bisphenol A bpa quality, high consumption, large amounts of three wastes (waste gas, waste water, and solid waste), severe equipment corrosion, and low yield. The sulfuric acid method was eliminated overseas in the 1960s.
The method using hydrochloric acid or hydrogen chloride gas as a catalyst is called the hydrochloric acid method. The hydrochloric acid method has a mature production process and can be produced intermittently or continuously. The consumption of raw materials and public engineering is low, and the product can reach high quality after refining, which is used in the production of polycarbonate. Due to the strong corrosiveness of hydrochloric acid, the material requirements for equipment, pipelines, and instruments are high, so the investment and maintenance costs are high. Like the sulfuric acid method, the three wastes are serious. The hydrochloric acid process was the main production method in the world in the 1970s and 1980s.
